I am not worried about an Extinction event. That was Doer not me.
I also know that the particles are not water soluble.
How much radiation can fish and water mammals take before it is a lethal dose?
lethal as in radiation sickness or long term cancer risks?
i dont know exactly.
im unaware of reports of fish kills presently happening in the harbour area at fukishima (i wouldnt bet on long term cancer risks tho) the storage pools on the otherhand would be on the lethal side
as with all life on earth anything in the sea has to cope with natural radiation level. outside of the immediate area of fukishima its pretty much buisness as usual

[h=3][FONT=Arial, Helvetica]Human body[/FONT][/h]You are made up of chemicals, and it should be of no surprise that some of them are radionuclides, many of which you ingest daily in your water and food. Here are the estimated concentrations of radionuclides calculated for a 70,000 gram adult based ICRP 30 data:
